N2 - Vaccines to protect against tuberculosis (TB) are urgently needed. We performed a case-control analysis to identify immune correlates of TB disease risk in Bacille Calmette-Guerin (BCG) immunized infants from the MVA85A efficacy trial. Among 53 TB case infants and 205 matched controls, the frequency of activated HLA-DR + CD4 + T cells associates with increased TB disease risk (OR=1.828, 95% CI=1.25-2.68, P=0.002, FDR=0.04, conditional logistic regression). In an independent study of Mycobacterium tuberculosis-infected adolescents, activated HLA-DR + CD4 + T cells also associate with increased TB disease risk (OR=1.387, 95% CI=1.068-1.801, P=0.014, conditional logistic regression). In infants, BCG-specific T cells secreting IFN- 3 associate with reduced risk of TB (OR=0.502, 95% CI=0.29-0.86, P=0.013, FDR=0.14). The causes and impact of T-cell activation on disease risk should be considered when designing and testing TB vaccine candidates for these populations.
